Police say four people have died and over a dozen are injured after a speeding stolen car struck a trailer attached to a bus in San Antonio.

The shuttle company, Transportes Guerra, is based in Fort Worth. CBS News Texas spoke with the family who runs the business and confirmed that the owner, Jose Hector Guerra — also known as "Tito" — was among those killed. He leaves behind a wife and children.

Police said four suspects who were inside the stolen car when it crashed are at large, including one person carrying an assault rifle.
